Hello i am new to this site but i have a question that may or may not be simple.
 I really like the wicked one sub its easy,cheap and small for a horn.
I want to try to cut it in half. I would like to end up with a single woofer horn.
My question is how to i change the horn throat. Ill refer to the box as if you are looking at the layout on the work bench. If i omit the right woofer and enclosure should i narrow the entire horn so the flare has the same shape and angles or should i simply add a panell down the center line so that one side of the flare is angled and the other side is flat?

 I figure it should work if i move the right side horn wall to the left until its at the center of the little apex located at the back.
